#1
REVIEW
Calum A Arthur, Nicolas Bastardoz, Robert Eklund
Borrowed from organizational psychology, the concept of transformational leadership has now been applied to a sport context for a decade. Our review covers and critically discusses empirical articles published on this growing topic. However, because the majority of studies used cross-sectional designs and single-source questionnaires to tap what has been a fuzzy construct, current theoretical and methodological issues impede understanding of whether transformational leadership matters for sport outcomes. To make a difference to applied practice and policy, the transformational leadership construct requires a refined definition and stronger empirical tests allowing for robust causal inference...

BACKGROUND: End-of-life communication becomes increasingly difficult in terminal cancer, which inevitably entails conversations around dying and death. In resource-limited areas, the context of end-of-life communication is usually home-based palliative care comprising mostly women in the family who play critical roles as informal caregivers. This article examined the content and contexts of family end-of-life conversations and decisions based on the retrospective accounts of a sample of bereaved women family cancer caregivers in Nairobi, Kenya...

Lung cancer, primarily non-small cell lung cancer (NSCLC), is the leading cause of cancer mortality and the prognosis of patients with advanced or metastatic NSCLC is poor. Despite significant advances in diagnosis and treatment, little improvement has been seen in NSCLC mortality. Recently, Intratumoral Chemotherapy, a direct local delivery of chemotherapeutic drugs, has shown promise in clinical studies. However, toxicity and high dosage of chemotherapeutic agents used for treatment are a limitation. Moreover, these drugs damage indiscriminately, cancerous as well as normal tissues...

The major issue in coronary heart disease (CHD) diagnosis and management is that symptoms onset in an advanced state of disease. Despite the availability of several clinical risk scores, the prediction of cardiovascular events is lacking, and many patients at risk are not well stratified according to the canonical risk factors alone. Therefore, adequate risk assessment remains the most challenging issue. Recently, the integration of imaging data with biochemical markers in a radiogenomic framework has been proposed in many fields of medicine as well as in cardiology...

REVIEW
Bence György, Casey A Maguire
Gene therapy, the ability to treat a disease at the level of nucleic acid, has journeyed from science fiction, to hard lessons learned from early clinical trials, to improved technologies with efficacy in patients for several diseases. Adeno-associated virus (AAV) vectors are currently a leader for direct in vivo gene therapy. To date, AAV is safe in patients, with clinical benefit in trials to treat blindness, hemophilia, and a lipid disorder, with many more trials underway. Despite this remarkable progress, barriers exist for AAV vectors to be effective gene transfer vehicles in all organ/cell targets, as well as patient subpopulations...

Therapeutic breakthroughs in a number of retinal degenerative diseases have come about through the development of biotherapeutics administered directly into the eye. As a consequence of their use, we have gained more insight into the immune privileged status of the eye and the various considerations that development, manufacturing, and use of these drugs require. It has been observed that therapeutic proteins injected into the vitreous can elicit an immune response resulting in the production of anti-drug antibodies (ADAs) which can have clinical consequences...

Dental radiology uses X-ray technology to diagnose and design treatment of various clinical problems related to the oral cavity and surrounding tissues. As technology quickly evolves, there are numerous X-ray modalities using different tools in the attempt to best image and treat efficiently these diseases, disorders or other related clinical conditions. The reported numbers of dental X-rays, the fact that these may be under-reported in many countries and because dental X-rays are performed more on younger individuals, whose teeth and dentition are still developing, calls for increased need on radiation protection...

Adult sex ratio (ASR, the proportion of males in the adult population) is a central concept in population and evolutionary biology, and is also emerging as a major factor influencing mate choice, pair bonding and parental cooperation in both human and non-human societies. However, estimating ASR is fraught with difficulties stemming from the effects of spatial and temporal variation in the numbers of males and females, and detection/capture probabilities that differ between the sexes. Here, we critically evaluate methods for estimating ASR in wild animal populations, reviewing how recent statistical advances can be applied to handle some of these challenges...

REVIEW
Sixun Yang, Doran Fink, Andrea Hulse, R Douglas Pratt
Chikungunya virus (CHIKV) is a mosquito-transmitted alphavirus. Chikungunya disease (CHIK) in humans is characterized by sudden onset of high fever, cutaneous rash, myalgia and debilitating polyarthralgia. Until recently the virus was considered endemic to only Africa and Asia, but since 2004 CHIK has spread to previously non-endemic regions, including Europe and the Americas, thereby emerging as a global health threat. Although a variety of CHIKV vaccine candidates have been tested in animals, and a few have advanced to human clinical trials, no licensed vaccine is currently available for prevention of disease...

Planning can be defined as action selection that leverages an internal model of the outcomes likely to follow each possible action. Its neural mechanisms remain poorly understood. Here we adapt recent advances from human research for rats, presenting for the first time an animal task that produces many trials of planned behavior per session, making multitrial rodent experimental tools available to study planning. We use part of this toolkit to address a perennially controversial issue in planning: the role of the dorsal hippocampus...

BACKGROUND/PURPOSE: Surgery followed by radioiodine is a mainstay of treatment for thyroid cancers of follicular origins. However, about 5% of the thyroid cancers are non-operable and/or radioiodine-refractory diseases, which are either locally advanced or metastatic and result in a survival of less than 5 years. How to treat this population of thyroid cancer patients becomes a critical issue requiring further understanding of the tumor's genetic information. METHODS: We used formalin-fixed paraffin-embedded specimens of 22 fatal thyroid cancers and their corresponding non-tumor parts, if available, to yield genomic DNA, and applied the Ion Torrent™ Personal Genome Machine (IT-PGM) System (Life Technologies), a next generation sequencing technology, to interrogate 740 mutational hotspots in 46 oncogenes...

Larry Vandervert
BACKGROUND: Mathematicians and scientists have struggled to adequately describe the ultimate foundations of mathematics. Nobel laureates Albert Einstein and Eugene Wigner were perplexed by this issue, with Wigner concluding that the workability of mathematics in the real world is a mystery we cannot explain. In response to this classic enigma, the major purpose of this article is to provide a theoretical model of the ultimate origin of mathematics and "number sense" (as defined by S. Dehaene) that is proposed to involve the learning of inverse dynamics models through the collaboration of the cerebellum and the cerebral cortex (but prominently cerebellum-driven)...
